Comment: Why a 7-day moving average? Wisconsin tends to have cyclical patterns in testing results, with low spots typically on Mondays (this may be due to lower testing on weekends)
Active cases: Estimated recovery time from health experts varies between 10-20 days, with a nontrivial proportion of cases being long-term / on-going. Even given the testing lag, a conservative approximation is to use the total number of positive (diagnosed) cases across the last 10 days. We will go with this standard, along with a range from 10-14 days of active accumulation, and adjust as more precise information becomes available. 14 days corresponds with two-week standard in place in MN school decisions.

Re-opening Trends: that is, why didn't the first wave end?
I devised plots that are similar to those found, for example, at the following locations:
Masks Should I wear a mask in enclosed public spaces? Unequivocally, YES. References for reasoning, using a current (as of July 8) accumulation of over 70 references. A few of my favorites (modeling-wise) are:

Predicting cumulative deaths in state
[1] "The number of cumulative deaths, at a lag of 21 days, are approximately 24.3 times number of cumulative cases to the 0.35 power."
[1] "We thus predict that on 2020-09-12 the cumulative number of deaths in WI will be 1182"
